## glow preview (see child nodes).

## NEO-22: WASD locomotion + `move-stream` samples (see `player.gd` / `position_authority_client.gd`).
|
|
## NS-23: bakes `NavigationRegion3D` on startup; boot snap from authority `GET`.
|
|
## NEO-15: follow camera is `World/IsometricFollowCamera/Camera3D`
|
|
## (see `isometric_follow_camera.gd`).

## Prototype: two random short bumps (sibling StaticBody3D under NavigationRegion3D; see
|
|
## `random_floor_bumps.gd`) before nav bake.
|
|
## Prototype: `PhysicsRampTest*` (+X extension: west slab ends before the dip;
|
|
## `PhysicsRampTestFloorExtensionNorthFill` / `SouthFill` restore walkable floor past the dip in ±Z;

|
## block; gentle ramp on **+Z**; steep on **+X**), plus `PhysicsSmoothHillTest` /
|
|
## `PhysicsSmoothDipTest` (HeightMap collision).
|
|
## Steep ramp: **2 m / 1.5 m** rise/run (~53°) so slope exceeds `Player` `floor_max_angle` (~50°)
|
|
## and is not walkable; gentle ramp stays shallower than `NavigationMesh.agent_max_climb`. Steep is
|
|
## under `World` only (not nav source geometry).

## Dev smoke (NEO-18 occluder): action [code]dev_toggle_occluder_obstacle[/code]
|
|
## (default **Ctrl+Shift+K**). Toggles `Obstacle` **visibility + collision** —
|
|
## does not call [method Node.queue_free].
|
|
## Uses [member Node.process_mode] [code]PROCESS_MODE_DISABLED[/code] so the [StaticBody3D] is
|
|
## **removed from the physics simulation**
|
|
## (default [member CollisionObject3D.disable_mode] is [code]REMOVE[/code]).
|
|
## Layer/shape tweaks alone left a **Jolt ghost collider** (invisible wall) in practice.
|
|
## When hidden, reparents `Obstacle` under [member _world]: [NavigationMesh] source geometry scans
|
|
## [NavigationRegion3D] children only ([code]SOURCE_GEOMETRY_ROOT_NODE_CHILDREN[/code]), and the
|
|
## default [code]geometry_parsed_geometry_type[/code] is [code]PARSED_GEOMETRY_BOTH[/code], so a
|
|
## child [MeshInstance3D] still carved a hole even with collision disabled — rebake alone was not
|
|
## enough.
|
|
## After each toggle, rebakes (main thread) and syncs the player [NavigationAgent3D].
|
|
## **F9** / **F10** are debugger shortcuts in the embedded game; use the Input Map action.
|
|
## For a true **freed-node** occluder test, reload the scene or remove the body in the editor.
